问题描述:
There is a pen and an eraser in the box否定句和一般疑问句和a pen and an eraser 划线提问
答
否定句在be动词情态动词后面加not,没有be动词和情态动词时加助动词,注意加入主动此时要考虑时态和人称.
一般疑问句:如果原来的陈述句中含有be动词或者情态动词,那么直接把be动词或者情态动词往前提到句首即可.如果没有,则跟改否定句一样要先加入与时态人称相适应的助动词再提前到句首.
特殊疑问句(对划线部分提问):在一般疑问句的句式前加上相应特殊疑问词,去掉划线部分.
There isn't a pen or an eraser in the box.注意改为否定句时,一般用or来代替and,但还是翻译成“和”.
Is there a pen and an eraser in the box?
What is there in the box?
